Tune Up is a folk music fanzine published by the Philadelphia Folksong Society from Philadelphia, U.S.A.

Subtitled, "The monthly newsletter of the Philadelphia Folksong Society", this publication began in January 1963 as a 12 page, 8.5" X 5.5" fanzine covering the folk-song revival scene in Philadelphia as well as covering international performers such as Peter, Paul and Mary, Joan Baez, Don Crawford, and Hedy West. Early issues were edited by Janet Hauguel. It was available mainly for members of the Society.
